A male who does not like to get his cock out in public places, he will often shy away from streaking lunatics or nudist societies.

Jenny: I asked him to get his dick out at the rock show
Elda: Really? What did he say?
Jenny: He wouldn't, I only wanted to suck his long shosh
Elda: He has his cock in a tree
Jenny: Sure has, my last boyfriend used to love throwing his cock out of his tree.
Elda: Oh yeah Dave! Sure! They used to call him soil dick because his cock was never up in a tree always on the ground rolling in soil.
